Either gplay or gst-launch can not decode MP3 audio in the clip.
In the info that gplay printed, there is a line:
no decoder available for type 'audio/mpeg, mpegversion(int)1, mpegaudioversion=(int)1, layer=(int)3, rate=(int)44100, channels=(int)2, parsed=(boolean)true'
The codec version is 3.0.7, I have tied 3.0.1 with the same video clip, both video and audio can be decoded, audio is perfect but the video come out one frame every second.
MP3 audio is very common for us, and I notice there is a plugin ffdec_mp3 can decode mp3 audio. Can anyone tell me how to decode h263/mp3 clip smoothly on iMX6 ubuntu platform.
